Karanbir Cheema, whom everyone called Karan, had a serious allergic reaction with a fatal outcome. Cheema was severely allergic to all dairy products, as well as wheat, nuts, gluten, and eggs. He also suffered from asthma and atopic eczema.

The tragic incident happened in Greenford, West London, in June last year. The school immediately called 999, saying it was “just an allergic reaction,” but when the paramedics arrived they saw Karan “gasping for air.”

The boy shortly stopped breathing and went into anaphylactic shock. He remained unconscious while paramedics tried to save his life. Another 13-year-old boy was then arrested on suspicion of attempted murder. However, no charges were brought against him.

This is not OK. No child who lives their life under the shadow of life threatening food allergies should have to die like this. Better education in schools and of the public around food allergy has to be made a priority. https://t.co/OLu3cn49Vk

The boy who threw that #cheese to the #victim knew what he was doing and the consequences of that must be tried as an adult and be punished as an #adult.Cause he is a #killer.He's mentally matured enough to kill someone which he did.Regardless of his age. https://t.co/3zTMz7743R

Deadly food allergies

For some people who have a food allergy, even a tiny trace of it can be deadly. Over 15 million people suffer from food allergies in the United States alone. 1 in every 13 children has this condition, which is about 2 kids in every classroom.

The most common allergens are nuts, wheat, eggs, milk, soy, and fish. To help someone, who has an allergic reaction, you need to know the signs. The most common of them include trouble breathing or swallowing, shortness of breath, repetitive cough, swelling of tongue or lips, in some cases repetitive vomiting or diarrhea.
